Overview

This screen is accessed from the back-end Joomla! administrator panel. It is used to enable/disable/uninstall extensions that are installed in your Joomla! installation. Some examples of extensions are plug-ins, components, and site templates.

How to Access

Select Extensions → Extension Manager from the drop-down menu of the Joomla! Administrator Panel. Then select the Manage menu item in the Extension manager screen that appears.

Description

This screen allows you to Enable/Disable extensions. To Enable/Disable an extension is the same as to Publish/Unpublish it. In addition you can uninstall extensions from this screen as well.

Column Headers

Checkbox. Check this box to select one or more items. To select all items, check the box in the column heading. After one or more boxes are checked, click a toolbar button to take an action on the selected item or items.

Name. The name of the extension.

Extension Type. The extension type. Some examples of extension types are module, plug-in, template, or language.

Enabled. A green circle with a check mark or a red circle showing whether the use of the extension is enabled/disabled. Click the icon to toggle the item between enabled and disabled.

Version. The version number of the Extension.

Date. The date this extension was released.

Folder. If the extension is a plug-in, the subdirectory of your Joomla! installation's /plugins directory where the extension is located. By default Joomla! 1.6 has the following subdirectories in the plugins directory which each represent the different types of plug-ins that are defined: authentication, content, editors, editors-xtd, extension, search, system, user.

Client. Specifies if this is a site or administrator extension.

Author. The author of this extension.

Id. The ID number. This is a unique identification number for this item assigned automatically by Joomla!. It is used to identify the item internally, for example in internal links. You can not change this number.

Display #. The number of items to display on one page. Note that if you have a large number of items, it may be helpful to use the Filter options, located above the column headings, to limit which items display (where applicable).

List Filters

The list of extensions which appears on this screen may be very large. You can use one of the available filters or any combination of them to limit the number of extensions displayed to just the extensions which match your filter parameters.

Filter by Partial Name

If you have a large number of extensions in the list, you can use this filter to find the desired extension(s) quickly. Enter either all or part of the extension name and press 'Search' to display the matching extensions. For example, "joom" will match all extension names with the word "Joomla!" in them. This filter is not case-sensitive.

Hide Protected Extensions

Check this checkbox to hide extensions which are protected.

Filter by Extension Type, Plug-in Folder, and Extension Client

Select type. Select the extension type from the drop-down list box of available types.

Select folder. Select a plug-in folder from the drop-down list box of available folders. There is a separate folder for each type of plug-in defined in your installation of Joomla!.

Select client. Select an extension client from the drop-down list box of available clients. There are two clients - Site and Administrator. Site clients are extensions which are designed for use in areas outside of the administrator interface. Administrator extensions are for the back-end administrative functions of your Joomla! installation. Usually you would only directly interact with these extensions through the administrator web interface.

Toolbar

At the top right you will see the toolbar:

Publish. Enable the selected extension(s).

Unpublish. Disable the selected extension(s).

Refresh cache. Refresh the information displayed for the selected extension(s).

Uninstall. Uninstall the selected extension(s).

Options. Opens the configuration window for the Extension Manager. In this window you can set Extension Manager access permissions for each user group specified in your Joomla! installation.

Quick Tips

Throughout the administrator interface of Joomla! you will see the terms "Publish" and "Unpublish". Publish means the same thing as Enable or Activate. Unpublish means the same thing as Disable or Deactivate. You may see the terms used interchangeably in extension screens and help documentation you find online.

Some information such as Date or Author may not be displayed for an extension. This is not a problem. It merely means the information was not specified by the extension developer in the extension's installation package.
